Just purchased a:

3in1 Soil Moisture/Humidity Light PH Tester Meter for Plant Flowers Fruits added to soil

Which looks like this:

Attachment 296708

Soil Tester:

Attachment 296709

My question is: Do i leave the soil probe in the soil 24/7 and just just flip the switch when i want my 3 readings, or do i take it out every single day and clean it then re insert it the next day when i want another reading? I'm just worried about damaging the roots if you see what i mean?

Thanks,
